I don't have a daughter. DiL said something about shopping with her for wedding dress and bridesmaids' dresses. But I'm a 5 hour drive away and things just didn't work out. Of course she took her mum. However....I did get preview photos of everything before anyone else, so felt I was being kept in the loop.
I was also asked to do one or two things for the wedding itself, which was nice. I feel a bit left out, though, when I saw the official wedding photos as there were loads of her parents and a few of my DH but virtually none of me and few of our family. That wasn't her fault, just the eccentricities of the photographer.
And, looking at what photos there were of me, I find myself wishing I'd chosen another outfit. 
In the end, it was a lovely day, and it was their day, not mine.
Maybe you could ask if there's anything you can contribute - perhaps you have artistic/photographic skills that would complement the other arrangements on the day and make you feel more involved.
